To all whom it may concern:

Be 1t known that l, Anvin JOHNSON, a subject of the Emperor of Russia, residing at "Duluth, in the county of St.' Louis and State` ol' Minnesota, have invented a new and useful Saw-Set, of which the following is a specii-,ication lily invention relates to improvements in saw-sets; and the object is to provide a sav:- setthat will be'eilicient and also convenient for use in lumber camps and like places, for setting the teeth of saws 'used in felling trees.

ln the accompanying drawing, Figure 1 is a side elevation of my improved saw-set mounted upon a piece of lumber serving to support it when in use, and a portion of a saw blade in position to Abe set by the device. F ig. 2 is a top view oit' Fig. 1 with the wooden supporting block omitted. Fig. 3 is a trausverse section on the line own in Fig 1 with y the wooden blockornitted,

Referring ,tio the drawing by reference nu merels, 4 designates the steel block serving as the anvil inthe device. it 1s securable to ymost-ly any kind oi Wooden support 5 by having in a notch 6 in one end of it pivoted at 7 an angularly bent prong or hook 8 adapted to be driven horizontally into the wood, and near the other end of it a bottom prong 9 adapted to be Adriven downward into the wooden bloeit, plank or log @n 'the pivot Lf is also attached a liantg lever 1G, which bears at 11 upon the free end oi another lo ver l2, which is pivoted at i3 in notch in the iront end ot' t he t 'il Through apertures 27 in both oiE said levers is guided to 'slide vertically the punch 1d by which the saw 'teeth are set when the punch receives a blow on its upper end. The lower 'end of the punch and the part ci' the Yace of the anvil operated upon are therefore beveled to the extent desired to have the sai-v teeth set, es nan be seen in -`Eig` 1, where l5 is the saw and i6 a tooth voperated on after it has been placed a gage 17. Said gage is guided by having lingers 18 (see Fig. 3) movably guided in grooves 19,'which in both sides of the anvil entend parallel to the beveled race 20 thereof. The plate is held in any forward or rearward position by having an erin 2l with a slot 22 in it for a thumb-screw 23 which is threaded in the side of the anvil and thus able to hold the arm clamped thereto in any adjusted position according to the length oi the saw tooth or part of it tihat is to be set. The saw, while operated on, is

held lirmly down on'the anvil vby a arm 24 secured at 25 to theanvil and having its front end curved upward so as to receive..V

pressure from the lower lever 12 ofthe corni vpound levers -104-12; theoperator bearing down on the lever 10 with one hand while striking on the punch with a hammer-held in the other hand; and when he raises the lever 10 the spring 24 raises from the saw-blade and by the lever 12 and a pin 26 in the side of the punch also vlifts the punch, so that the saw blade is free to be moved with the next tooth into posit-ion for operation, Which-is thus repeated until all the teeth are set. The apertures 27 are elongated in longitudinal direction of the levers and upon each lever is held by a thumb-screw 28 a plate 29 having a slotted hole for said thunlb-screw4 and a guiding hole for the punch 14 so that by adjusting the plates by, said thumbscrews the punch is adjusted so as to cover more or 'less of the beveled face of the anvil. From this it will be understood that the guide 17 and punch 14 may bev moved rearwardly on the anvil until even the shortest saw` teeth may be set by the device.

Having thus described my invention, what l claim is l. The combination with an elongated steel anvil having near one end of its u per side a beveled or inclined face on whic to set the saw teeth, a setting punch arranged to slide vertically above said face, a s r1ng arm thved near the other end ofthe anvi and extending toward the end having the beveled lace, said arm having its body odsetfromy the anvil to permit the saw blade to pass below it, and its free end curved upward higher than the body, end of the anvil and'adapted to press upon the end of the spring arm and thus hold the saw firmly upon the anvil, a saw-setting punch slidingly inserted vertically in an aperture in the lever and having its lower end beveled parallel to the beveled face of the anvil, and means whereby the lever will engage the punch and elevate it.

2. rl`he combination with an elongated steel anvil having near one end of its upper side a beveled or inclined face on which to set the saw teeth, a setting punch arranged to slide vertically above said face, a spring arm fixed near the other end of the anvil and extending'- toward the end having the beveled face, said arm having its body ollset troni the anvil to permit the saw blade to a lever pivoted at one savT firmly upon. the anvil, e sawsettingA punch slidin ly inserted vertically in an aperture 1n t e lever and havinlr its lower end beveledjparallel to the beveled face of' the anvil," and means whereby 'the lever will engage the punch and elevate it; a second lever pivoted to the other end of the anvil and adapted ,to press u on the lirst mentioned lever, said second ever also having an aperture' for guiding' the setting punch.

3. The combination with an elongated steel anvil having near one end of its upper side a beveled or inclined face on Whichto set the saw teeth, a setting punch arra` ged to slide vertically above saidface, a sng arm fixed near the other end of the anvil and extendin toward the end having the beveled face, sai arm having its body oilfset Jfrom the anvil to permit the saw blade to pass below it, and its free end curved upward higher than the body, a lever pivoted at one end of the anvil and adapted to press upon the end el' the spring arm and thus hold the `saw iirmly upon the anvil, .a saw setting punch slidingly inserted vertically in an aperture in the lever and having its lower end beveled .parallel to they beveled face of theanvil, and means whereby the lever will engage the punch and elevate it; a second lever pivoted to the other end of the anvil and adapted to press upon the-first mentioned lever, said second lever also having an aperture for guiding the setting punch, the apertures in said levers being elongated in longitudlnal direction of the levers, a guiding `plate adjustablysecured on each lever and guidingly engaging the punch, for the purpose set forth. f' In testimony whereof I aix my signature,

JOHNSON.
